Check if NAO is listening, his eyes should be navy blue.
For further details, see: How I know NAO is listening.
Say a short sentence, in one go.
Pauses are interpreted as the end of the sentence, so do not hesitate: speak loud and clear, without hesitation.

|Start activity_name||Lance activity_name|
|Activity trigger sentence||Activity Trigger sentence|
Exiting an Activity ¶
To stop an Activity currently running:
|Lay your hand on the three Head tactile sensors for 3 to 10 seconds.|
Remove your hand.
The current Activity is stopped.
Note: if there was no running Activity, NAO reacts as if you stroked his head.
NAO has fallen ¶
NAO tries to recover the last stable posture he was in (sitting or standing) and will not stop trying until this posture is recovered.
When a try fails, NAO removes its Stiffness so a human can put NAO in a more favourable position, (sit or crouch) so NAO’s next attempt will be successful.
Understanding interaction ¶
How NAO detects humans ¶
NAO tries, as much as possible, to establish and keep eye contact with people around.
To do so, NAO:
|A||Looks in the direction of any detected stimulus - sound, movement, touch.|
Checks if this stimulus may correspond to a human.
NAO does not react to new stimulus:
When processing a stimulus (i.e. checking if it corresponds to a human).
NAO does not react to other stimuli until he has finished to process the first one.
When engaged in an Activity or a Dialog.
When NAO is chatting with a human, he always keeps tracking the human until the human has left.
When NAO is in the middle of an Activity, all his actions are exclusively defined by the Activity itself.
How I know NAO is listening ¶
To make sure NAO is listening, check his eye LEDs, and pay attention to the slight “blip” sounds.
Eye LEDs feedback
|When the eye LEDs are ...||NAO is ...|
|Navy blue, rotating||listening.|
|Green||not listening anymore, he is processing what the human just said.|
|White or pale blue||not listening, the dialog has not started.|
Additionally, slight “bilip” sounds can be heard when NAO starts and stops listening:
- when starting listening, the sound is ascending,
- when stopping the sound is descending.
